Abstract

PURPOSE: To make the weld penetration uniform and to heighten the weldabity, by forming annular weld joint part on the water room side circumference of tube hole on the tube plate and welding the tip end of tube inserted in the tube hole and annular weld joint part.
CONSTITUTION: The annular groove 14 having radius R being 1W2 times of the tube thickness t, is formed on the outer circumference, leaving behind the annular joint part 10A having 1W2 times width of the thikness t of the tube 13, on the face of the water room 12 side of the tube hole 11 on the tube plate 10. Next, the tube 13 is inserted in the hole 11. Hereby, a good welding is attained uniformly penetrating the tube, for example, thin tube of corrosion resisting metals, such as Ti, Zr, Ta etc., or Cu tube and joint part, by welding 15 the tube tip end 13a and part 10A.
